NXP Semiconductors MWCT1014SFVLLN

Overview

MWCT1014SFVLLN from NXP Semiconductors is a pre-production Arm® Cortex-M4F microcontroller designed for wireless charging control applications, operating from 2.7 V to 5.5 V across -40 °C to 105 °C ambient, featuring 512 KB flash with ECC, 128 KB SRAM with ECC, and integrated CSEc cryptographic engine.

For engineers reviewing the MWCT1014SFVLLN datasheet, MWCT1014SFVLLN pinout, MWCT1014SFVLLN application, or MWCT1014SFVLLN equivalent, key selection considerations include HSRUN mode support up to 112 MHz (with RUN mode required for CSEc/EEPROM operations), dual 12-bit ADCs (up to 32 channels each), FlexCAN with optional CAN-FD, and 64-pin LQFP package compatibility with other MWCT101xS family members.

Technical Context

The MWCT1014SFVLLN implements an Armv7-Architecture-based Cortex-M4F core with single-precision FPU and DSP extensions, supporting up to 112 MHz in HSRUN mode (1.25 DMIPS/MHz) and 80 MHz in RUN mode-where CSEc security operations and EEPROM emulation are permitted. Its clock system integrates SOSC (4–40 MHz), FIRC (48 MHz), SIRC (8 MHz), LPO (128 kHz), and SPLL (up to 112 MHz).

Power management includes five operational modes (HSRUN, RUN, STOP, VLPR, VLPS), with PMC-enforced constraints: CSEc execution and FlexNVM writes are prohibited in HSRUN mode and require transition to RUN mode (80 MHz). Memory subsystem features 512 KB program flash with ECC, 64 KB FlexNVM for data flash/EEPROM emulation, and 128 KB SRAM with ECC.

FAQ

What is the maximum operating frequency of the MWCT1014SFVLLN, and under what conditions is it valid?

The MWCT1014SFVLLN achieves up to 112 MHz in HSRUN mode, but this frequency is restricted to compute-intensive tasks only. CSEc cryptographic operations, EEPROM emulation, and Flash writes must be executed in RUN mode at 80 MHz. This constraint is enforced by hardware error flags if violated, requiring explicit software mode transition before security or non-volatile memory access.

Does the MWCT1014SFVLLN support CAN-FD, and how is it implemented?

Yes, the MWCT1014SFVLLN includes three FlexCAN modules, one of which supports CAN-FD (Controller Area Network with Flexible Data-Rate) per the ISO/CD 11898-1 specification. CAN-FD operation requires enabling the FD bit in the MCR register and configuring the bit timing registers for both nominal and data phases; it is validated for use in automotive wireless charging status reporting over CAN-FD networks.

How does the MWCT1014SFVLLN handle memory protection for functional safety compliance?

The MWCT1014SFVLLN implements a System Memory Protection Unit (System MPU) at the Crossbar Switch level-not the Arm Core MPU-to enforce access rights for all masters (CPU, DMA). This allows independent permission settings per memory region (e.g., flash, SRAM, peripheral space), satisfying ASIL-B requirements per ISO 26262 without relying on core-integrated MPU hardware that is absent in this Cortex-M4F variant.

What ADC capabilities does the MWCT1014SFVLLN offer for wireless charging current sensing?

The MWCT1014SFVLLN integrates two independent 12-bit SAR ADCs, each supporting up to 32 analog input channels and 1 MSPS sampling rate. For current sensing, they can simultaneously digitize shunt voltage and resonant tank current with hardware-triggered conversions synchronized to FlexTimer PWM edges-enabling cycle-by-cycle peak current limiting and real-time impedance calculation essential for foreign object detection.

Is the MWCT1014SFVLLN pin-compatible with other devices in the MWCT101xS family?

Yes, all MWCT101xS devices sharing the same package (e.g., 64-pin LQFP) are pin-to-pin compatible, including MWCT1014SFVLLN, MWCT1015SFVLLN, and MWCT1016SFVLLN. This allows hardware reuse across product tiers-only firmware and configuration need adjustment when upgrading flash size or peripheral features-reducing design iteration time and qualification effort.
